hey k i have a 1.7cm macroadenoma as well and it was found about the same time i became ill with cfs. i have bad bad eye pain in the left eye only. my tumor is close to the optic chiasm and i believe during times of stree the tumor enlarges just a little bit and puts presure on the nerve to my eye. the surgeons do not think so but i have had enough of medical school and working in the health care field to know, there are no absolutes. they will not do surgery on mine yet because it is behind the pituitary gland and towards the top. however all the articles i have read about the surgery, most people come out very good and some even go home the next day. i put pituitary macroadenoma in my search engine and there are all kinds of articles from hospitals that specialize in this kind of surgery ! i am due for another scan this month so i will see how it goes. good luck to you bill m inkc mo.
